This video is useful for changing a thermocouple on any L&L kiln - in particular an eQuad-Pro or a School-Master Kiln.

Be sure to maintain proper polarity.

In the USA:
Yellow Wire = PLUS (+)
Red Wire = MINUS (-)
The thermocouples are marked with a (+) and (-). Also the negative (-) is marked with a red marker. The negative wire is MORE magnetic than the positive wire.
